Code-block line numbers

Theme component
4

Please add the option to choose dark or light theme, because my discussion page defaults to light theme but in the code block it is dark theme customization in github style.

This is the state when the discourse page uses a light theme and the codeblock is set to display in dark github style

Here I also share some customizations about codeblock display on my discourse page.
Hope it will be useful to someone, and make their discourse page more interesting
